        }

    }

So i was supposed to do Word generator with words like Woodcutting,Agility,Fishing. etc but  this just generates random characters ? does anyone have any clue how i can generate words. Thanks in advance, for any questions i try answer fast as possible

I'm guess this homework? You've posted a lot regarding Java. Maybe you nee to learn yourself. Sorry for being blunt. You need to work on your own.

This isnt homework just my own project so i could learn java bit better by making java things that are interesting

this literally just loops in till the length of string_length adding a random chat for char_list. 

 

How did you expect it to do anything else?

even still as @Abdul201588 said maybe its time to actually learn some java because its pretty clear what that loop does.

being a "noob" is fine, everyone is a noob at some point. I suggest doing an online java course so you can get the basic logic down. input, output, loops, ifs and so on.

Indeed, if you are struggling with even basic flow control such as loops then you really need to concentrate on walking before trying to run.

This may very well be the ONE TIME people will agree....

On that we can indeed agree, it seems good for learning syntax and flow control  You may well find what you need there. After mastering some of the basics if you are looking for more real world based problem solving then I'd suggest having a look at Codewars.

Alright, thanks for advises, i know how to do basic java pretty well but im quite new on GUI java things, ill definetly do researching, as this is my project to make me better on java.

Well  GUI just maps functions to a graphical representation for the user to see.

 

should as pressing a button to do an action or getting input from the user. Instead of that input being in the command line you have a text box.
